'INSULATING STEAM-CONDUCTING PIPES.

SPECIFICATION forming part of Letters Patent No. 223,314, dated January 6, 1880.

Application filed November 10, 1879.

To all whom it may concern Be it known that I, JACOB BROSIUS, ot' Belleville, in the county of St. Clair and State of Illinois, have invented a new and useful Improvement in Insulating Steam-Conductin g Pipes, which improvement is fully set forth in the following speeitication and accompanying drawings, in which- Figure l is a perspective view of a steampipe laid according to my invention. Fig. 2 is an end view thereof. Fig. 3 is a longitudinal section in line x a', Fig. 2.

Similar letters ot reference indicate corre- My invention consists in packing steamconveyingpipes for power, heating, and other purposes in a box, anda secondary surroundingbox, with air-spaces between them, whereby the inner box is prevented from decay and the heat of the pipes is retained.

It also consists in interposing between the two boxes, at intervals, blocks, which serve to separate the boxes without interfering with the circulation of air between them.

It also consists of metal cleats for supporting the pipes on the inner box.

It also consists in forming the top of the outer box with a slant roof for directing water Referring to the drawings, A represents pipes or tubing for conveying steam from the generator to any desired place Jfor power, heating, and other purposes, the same being inclosed in a wooden box, B, having on its bottom or tloor, at intervals, metal cleats C, whose upper faces are curved or depressed to correspond to the cylindrical or other shape of the pipe, by means ot' which the pipes are rmly supported and sustained. in position.

Inclosing the box B is a secondary box, D, with an air-space, a', between them, and in said space are blocks E, which may be secured to the outer face of the inner box or inner t'ace oi' the outer box, or rest loosely between them, their object being to support the inner box and separate the two boxes in such manner that the air-space c is not closed, for which purpose said blocks are made short or narrow.

The top of the outer box is formed of or formed with sloping pieces, forming a slant roof, b b, whereby, when the box is in position, water is caused to new from the roof, and its injurious lodgment thereon thus prevented.

The boxes D B and pipe A are respectively formed in sections, coupled together until the required length is obtained, and adapted to be employed under or on ground, as desired.

The sections ot' the outer box, open at top, are properly laid in a trench or supported on the surface. rlhe inner box is then placed on the ioor of the outer box and the pipe A l0- cated either' through the end or open top of the inner box 5 and said pipe maybe wrapped with suitable paper, felting, or other heat-confining material. The tops of the boxes are then closed, and the system of laying the pipes and boxes continued as far as required; but the details or order otl placing the boxes and pipes may be varied-as, for instance, in locating the inner box within the outer box, running the two boxes in position, and then inserting the pipe andscrewing it to thelength previously laid.

It will be seen that each section of pipes is well insulated and protected by the inner and outer boxes, and the air-space a. that exists between the pipe and box B, and the air-space a between the two boxes, whereby the radi` ation of heat-first from the pipes and afterward from the boxes-is in a great measure prevented, and the pipes rendered inaccessible to cold and moisture to any great extent.

By these provisions steam may be conducted to remote distances without loss of vitality, and reach its destination in good service i'or engines, heaters, 85e.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. The steam-pipe A, in combination with the box B and secondary box D, having an intervening air-space, a, substantially as and for the purpose set forth.

2. The box B and box D, with the intervening air-space a, in combination with the steam-pipe A, with the intervening air-space a', substantially as and for the purpose set forth.

3. The box B andpipe A, with the pipe-snpwith the surrounding box D, having 2t slant porting cleats C C, combined and operating roof. b, substantially as and for the purpose 1o substantially as and for the purpose set forth. set forth.

4. The pipe A and the boxesV B D, with the 5 intervening air-space a, in combination with the blocks E E, substantially as and Jfor the 5 purpose set forth.

5. The box B, with pipe A, in combination J AGOB BROSIUS.
